216 " ENDEAVOUR " SCIENTIFIC RESULTS. 



Remarks. — I have specimens from the coast and seas round 

 New Zealand which belong to this species, though those which 

 I sent to Ehlers for identification were named by him as E. 

 antennata, Savigny. Those, however, which I have as 

 duplicates agree precisely with these Australian forms, and 

 if Crossland's analysis of Savigny 's species be accurate, 

 Ehlers' identification must be incorrect. In the first place 

 Crosslandi states that the acicula and tridentate acicular 

 chsetae are not black but yellow, that the gills are '' large," 

 and that they are figvired as nearly meeting across the 

 back ; that in the posterior segments, after a decrease in 

 the number of gill filaments, which are quite slender, there is 

 an increase before dying out at or near the hinder end. 

 Ehlers2 gives an account of a worm under the name E. 

 antetDuita from Chilian shores (p. 126) which does not agiee 

 wholly with Crossland's account, for the acicula are black, 

 and Ehlers says nothing about the increase in the posterior 

 gills. Moreover, in E. ayitemiata, Savigny, not only are the 

 tentacles moniliform, but the dorsal cirr also, anteriorly 

 multiannulate, posteriorly triannulate. At the same time 

 the Australian species has the same lower lip as Crossland 

 figures for E. antennata, and it appears that the two are 

 pretty nearly allied. 



Locs. — East of Maria Island, Tasmania, 78 fathoms. 



Near Storm Bay, Tasmania. 



Ten miles north of Circular Head, Tasmania. 



East coast of Flinders Island, Bass Strait. 



Off Babel Island, Bass Strait, 50-80 fathoms. 



North-east of Babel Island, Bass Strait, 100-170 fathoms. 



Fifteen miles north-west of Cape Jervis, South Australia, 

 17 fathoms. 



Between Port Stephens and Newcastle, New South Wales. 



Distribution. — New Zealand (Foveaux Strait ; Massacre 

 Bay, on west coast) ; Pegasus Bay, on east coast. 



Variations. — The gills vary (a) as to the point of com- 

 mencement, and (6) as to the maximum number of filaments. 

 Out of the twelve anterior ends I find that in six they com- 

 mence on the sixth chaetigerous segment, in four on the fifth, 

 while in two they do not begin till the seventh, and then as 

 quite small stout filaments. The largest number of filaments 

 usually occurs on about the eighth to the thirtieth segments ; 

 and it is only to the last two individuals in the list that this
